AMG® Technologies: Engines

 

NANOSLIDE® Technology


The heart of every AMG® automobile is its powerful engine. Some of those engines are hand assembled in keeping with the AMG®’s production philosophy of “One Man, One Engine” with each engine being built by one craftsman from start to finish.

Each engine employs NANOSLIDE®, an innovative, award-winning coating technology in which a twin-wire spraying technique is used. Iron and carbon wires are melted together and sprayed onto the inner walls of the aluminum cylinders which produces an incredibly thin and almost perfectly smooth mirror-like finish with pores in the material to hold oil, offering maximum lubrication and reducing internal friction between piston, piston ring, and cylinder walls by up to 50%.

This results in weight savings, better fuel efficiency, lower emissions, and increase in power to weight ratio, making the engines in AMG® more efficient, agile, and last longer.

  • AMG®-enhanced 2.0L inline-4 turbo engine (M260)

    AMG®-enhanced 2.0L inline-4 turbo engine (M260)


    The engine utilizes twin-scroll turbocharging to deliver higher performance with lower fuel consumption. It employs CONICSHAPE technology to minimize piston friction and better fuel efficiency by widening the cylinder bores at the lower end of the cylinder liners resulting in a conical shape that resembles the mouth of a trumpet.

    Maximum power output: 302 hp

    Peak torque: 295 lb-ft

    It is in the 35 variants of the A-class, CLA, GLA, and GLB models.

  • AMG-enhanced 3.0L V6 biturbo engine (M276)

    AMG®-enhanced 3.0L V6 biturbo engine (M276)


    The engine was further developed with large turbochargers for enhanced response and power as well as a tuned exhaust system. Designed with a 60-degree bank angle to eliminate the need for the balance shaft, there is a reduction in rotational losses in the engine and more efficient, smoother engine refinement.

    Maximum power output: 385 hp

    Peak torque: 384 lb-ft

    It is in the 43 variants of the C-class and GLC models.

  • AMG-enhanced 3.0L inline-6-cylinder turbo engine (M256)

    AMG®-enhanced 3.0L inline-6-cylinder turbo engine (M256)


    The engine has been systematically designed for electrification with a 48-volt battery, featuring EQ boost technology, intelligent turbo charging with an electric auxiliary compressor that guarantees excellent drivability with no turbo lag. An integrated starter-generator affords hybrid functions such as boost or energy recovery, while delivering the fuel savings of high voltage hybrid systems.

    Maximum power output: 429 hp

    Peak torque: 384 lb-ft

    It is in the 53 variants of the CLS, E-class, GLE, and GT 4-Door Coupe.

  • AMG® handcrafted 2.0L inline-4 turbo engine (M139)

    AMG® handcrafted 2.0L inline-4 turbo engine (M139)


    This engine is the world’s most powerful factory-offered four-cylinder engine. Replacing the M133 engine, it utilizes a twin scroll turbocharger with roller bearings and turbine wheels for optimal response to generate more power per liter of up to 211 hp/liter than any production vehicle. The engine makes use of both port and direct fuel injection to achieve its high power outputs. It is available in two specific outputs for the standard AMG® models (base version) and for the S models.

    Maximum power output: 387 hp (Base version), 421 hp (S model version)

    Peak torque: 354 lb-ft (Base version), 369 lb-ft (S model version)

    It is in the 45 variants of the A-Class, CLA, and GLA models. It will become part of the hybrid drivetrain for the new 2024 C 63 S E.

  • AMG® handcrafted 5.5L V8 biturbo engine (M157)

    AMG® handcrafted 5.5L V8 biturbo engine (M157)


    The engine is the first AMG® V8 engine to use a direct fuel injection system. Based on the M278 4.7L biturbo engine, it has a higher displacement of 5.5 liters with an upgraded larger piston bore and stroke. It has a forged steel crankshaft and connecting rods attached to hypereutectic-cast pistons. The modification of turbocharger boost pressure makes different output variances possible.

    Maximum power output: 577 hp

    Peak torque: 590 lb-ft

    It is in the 63 variants of earlier model years of the E-class, S-class, G-class, ML, GL, GLE, GLS, CL, CLS, and SL. After nearly a decade of production, it ended its run with AMG® in 2019, with the GLE 63 being the last model to have it.

  • AMG® handcrafted 4.0L V8 biturbo engine (M177)

    AMG® handcrafted 4.0L V8 biturbo engine (M177)


    The engine is another variation of the V8 engine that replaced the M157 engine. Unlike typical turbocharged engines, this V8 engine mounts its two turbochargers in the engine valley for compact design, low emissions, and optimum responsiveness. The “hot V” design takes advantage of the natural thermal load to seek the highest point where heat rises. The exhaust exits from the top of the engine directly into the turbochargers. Turbochargers keep spinning whenever the engine is running, and therefore, always providing pressure or boost, eliminating turbo lag at low RPM.

    Maximum power output: 630 hp

    Peak torque: 664 lb-ft

    It is in the 63 variants of the newer C-class, E-class, G-class, GLC, GLE, GLS, S-class Coupe, and the GT 4 Door Coupe.

  • AMG® handcrafted 4.0L V8 biturbo engine (M178)

    The engine in the GT series also utilizes a “Hot V” design and a dry sump oil system that uses oil when necessary from an external oil tank which allows it to be mounted lower in the chassis, bringing the GT’s center of gravity closer to the ground for better handling and stability.

    Maximum power output: 720 hp

    Peak torque: 590 lb-ft

    It is in the GT, GT S, GT C, GT R, and GT Black Series.

  • AMG® handcrafted 6.0L V12 biturbo engine (M275 & M279)

    AMG® handcrafted 6.0L V12 biturbo engine (M275 & M279)


    The twin-turboed, massively powerful engine operated in a smooth fashion that only a V12 can achieve, with a 3 valve per cylinder, single overhead camshaft (SOHC) equipped with air to liquid intercooling technology. The M275 was upgraded to the M279 engine in 2012 with reengineered, forged pistons and crankshaft, modified turbochargers, a new engine control unit, coil pack ignition system, and exhaust system. These upgrades led to even better reliability, fuel economy and lower emissions.

    Maximum power output: 603 hp (M275), 621 hp (M279)

    Peak torque: 738 lb-ft (M275, M279)

    It is in the 65 variants of the S-class. AMG® celebrated the last run of the biturbo V12 engine with the 2020 S 65 Final Edition.
